Supersymmetry in noncommutative superspaces
Non commutative superspaces can be introduced as the MoyalWeyl quantization of a Poisson bracket for classical superfields. Different deformations are studied corresponding to constant background fields in string theory. Supersymmetric and non supersymmetric deformations can be defined, depending on the differential operators used to define the Poisson bracket. Some examples of deformed, 4 dime...
متن کاملP-adic Superspaces and Frobenius
The notion of a p-adic superspace is introduced and used to give a transparent construction of the Frobenius map on p-adic cohomology of a smooth projective variety over Z p (the ring of p-adic integers). This article partially intersects with [9]; it contains the proofs omitted in [9] as well as some investigations into the important notion of a prorepresentable p-adic superspace.
متن کاملHarmonic Superspaces from Superstrings
We derive harmonic superspaces for N = 2, 3, 4 SYM theory in four dimensions from superstring theory. The pure spinors in ten dimensions are dimensionally reduced and yield the harmonic coordinates. Two anticommuting BRST charges implement Grassmann analyticity and harmonic analyticity. The string field theory action produces the action and field equations for N=3 SYM theory in harmonic supersp...
متن کاملHarmonic Superspaces in Low Dimensions
Harmonic superspaces for spacetimes of dimension d ≤ 3 are constructed. Some applications are given.
متن کاملThe Minkowski and conformal superspaces
We define complex Minkowski superspace in 4 dimensions as the big cell inside a complex flag supermanifold. The complex conformal supergroup acts naturally on this super flag, allowing us to interpret it as the conformal compactification of complex Minkowski superspace. We then consider real Minkowski superspace as a suitable real form of the complex version. Our methods are group theoretic, ba...
